Build a Basic Runpod Serverless API

Runpod's Serverless platform enables the creation of scalable API endpoints, and the tutorial provided offers a step-by-step guide to developing a basic worker that determines if a number is even, subsequently turning it into an API endpoint. Users need a local environment with Python, Docker knowledge, and the ability to build Docker containers, with all code available in the IsEven repository. The tutorial outlines creating a function that processes job inputs and returns results, and introduces runpod-python as a wrapper to manage API inputs. After testing the API locally and ensuring its functionality, the tutorial advises packaging the function into a Docker container and pushing it to a repository like Docker Hub. The final steps involve using Runpod's serverless templates to create an API endpoint and deploying it, with the option to test it using cURL or other online tools.
